The team produced a version of the mineral in which silver is replaced by lithium, germanium by phosphorus, and some of the sulphur atoms by halides (chloride, bromide or iodide), resulting in argyrodite-like structures.

A team led by Hans-Joerg Deiseroth in Siegen, Germany, reported in the journal Angewandte Chemie that the characterisation of the most conductive representative of the man-made argyrodite minerals was made of lithium, phosphorus, sulphur and bromine atoms.
